A real person answers, day or night
Old pipe eventually needs more than a patch
A line that's been cleared and relined repeatedly is telling you something, and at some point repair stops making sense next to a proper replacement. Call (02) 9072 0597, and someone who's actually looked at what's failing gives you a straight answer, not a standard line.
Why this ground shapes every install differently
Two things about the local terrain change how drainage gets designed and installed here:
- Slope drainage on this ridge has to be respected, not fought A line laid without properly surveying the block's actual grade toward Manly Dam will silt up at the first low point, so every install starts with the ground itself, not a standard layout.
- Rock and shale sit close to the surface in plenty of yards Excavation on this terrain takes more care and more time than digging through soft, sandy soil, which is exactly why the design gets finalised before any trench is opened.
Drainage repair and installation services we provide
Whatever the property needs, the approach starts with what the ground and the existing pipework actually require:
New drain installation
A new line gets surveyed for the correct fall and depth before a trench is opened, matching the pipe to the property's actual terrain rather than a generic layout that ignores how the block really slopes.
Damaged section replacement
Where a section is too far gone for relining, that length gets cut out and replaced with new pipe tied properly into the sound sections either side, so the whole line performs consistently, not just the new part.
Regrading and re-laying
A line that was never graded correctly gets re-laid to the fall it should have had from the start, addressing the chronic silting problem at its actual source rather than treating the same low point again next season.
Gully and pit installation
New or additional gully traps and stormwater pits get positioned to match how water genuinely moves across the block, so the system copes with real conditions rather than a textbook layout that ignores the slope.
Renovations are the easiest moment to fix old drainage
Extensions and bathroom renovations across the suburb's original 1940s and 50s housing stock regularly uncover drainage nobody knew was a problem:
- An open trench during a build is drainage's easiest access point Fixing a poorly graded or undersized line while machinery and trades are already on site skips a whole separate dig further down the track.
- A new bathroom or laundry needs drainage sized for real use, not guesswork Fixtures added to an original 1940s layout often overload a line never designed to carry that extra volume in the first place.
Common repair and installation problems we fix
Two situations account for most of the structural drainage work on these older blocks:
A line that silts up no matter how often it's cleared
When the same section keeps collecting debris regardless of how recently it was cleared, the actual fall of the pipe is usually wrong, and regrading it properly fixes the underlying cause rather than the recurring symptom.
Drainage that can't handle a renovation's new load
Extra fixtures tied into an undersized original line will eventually overwhelm it, and upsizing or rerouting that section properly during the build avoids a failure turning up right after everything's finished, tiled and painted.
Why getting the install right the first time matters
Drainage that's designed properly the first time avoids a long list of future problems:
- A poorly graded line fails slowly, then all at once Years of gradual silting can end in a sudden full blockage, usually at the worst possible moment rather than a convenient one.
- Retrofitting a fix later costs more than doing it right initially Correcting a badly designed line after paving, landscaping or a renovation is finished means undoing finished work just to reach the pipe again.
- An undersized system limits what the property can do next A future renovation or extension can be held up entirely by drainage that was never sized with any real growth in mind.
How it works
How we handle it, step by step
From the first assessment to a system built for this ground:
- 01
Call and tell us
Ring (02) 9072 0597 and describe what's happening, and a licensed plumber, not an answering machine, will tell you what it likely means, what to stop using, and when we can realistically be there.
- 02
Quote before work
Your plumber inspects the job properly, runs whatever diagnosis it genuinely needs, and hands you a single fixed written price covering the complete fix, with a $0 call out fee and nothing added afterwards.
- 03
Surveyed, then built to the ground's actual fall
The block's real grade gets checked before any trench opens, and the new or replaced line is laid and tied into the existing system to that surveyed fall, not an assumed one.
- 04
Backed for life
Everything we complete is covered by our Lifetime Labour Warranty, the promise that outlasts the job itself: if it's not right, we come back. No questions. No cost.
Why choose Your Plumber Allambie Heights
Fixed prices, kept
Every job is priced upfront in plain writing before any work starts, the invoice always matches that number, and weekend or late-evening timing changes nothing, because overtime rates simply don't exist here.
Licensed and insured
Your Plumber Allambie Heights works under licence #275278C with full insurance behind every job, and the compliance certificates that protect your home's paperwork trail arrive with the invoice, without you ever needing to ask for them.
Lifetime Labour Warranty
Workmanship here is guaranteed for life under our Lifetime Labour Warranty rather than for a warranty card's fine-print window, which says more about how the work is done in the first place than any advertisement could.
Genuinely local response
We work these streets constantly rather than commuting in from across Sydney, so the van reaching you has usually just left a job nearby, stocked for the faults the local houses actually develop.
Getting the fall right on a sloped block is a design problem before it's a digging problem, and it's exactly the kind of detail a crew working this terrain daily never treats as an afterthought.

Good questions, straight answers
Drainage installation questions, answered for Allambie Heights
When does a drain need replacing instead of just repairing?
Once a section is genuinely collapsed, crushed by ground movement or too far gone for a liner to seal properly, replacement becomes the sounder option, and a camera inspection tells us which situation we're in.
Can new drainage be installed without digging up the whole yard?
Often, yes, targeted excavation over the actual fault is usually enough, and only a full system replacement or a major regrade genuinely needs a wider trench across more of the property.
Do you install drainage for a renovation or a new extension?
Regularly, new bathrooms, laundries and extensions all need drainage tied properly into the existing system, sized and graded correctly from the design stage rather than fitted in as an afterthought.
How do you decide the fall and depth for a new line on a sloped block?
By surveying the actual grade of the block first, since a line that looks fine on paper can still run wrong once real ground levels and existing pipework are properly accounted for on site.
Is old clay pipe ever worth keeping instead of replacing?
Sometimes, a structurally sound section with no root damage can often be relined rather than replaced, and we'll always recommend the less disruptive option where the pipe genuinely still allows for it.
What warranty applies to new drainage installation work?
The same Lifetime Labour Warranty as every other job, so a fault in workmanship on a new install gets put right at no cost, with no separate shorter cover hidden in the paperwork.
